eToro Viewer
Last updated: 4 September 2026
The short version. You bring your own eToro keys, and they stay in your iPhone's Keychain. I have no server, so I never see your portfolio, your keys or your positions. The AI summary is the one thing that leaves the device: your holdings are sent to Anthropic's Claude API to be described in words.
There are no accounts, no tracking, no advertising and no analytics in this app. Nothing about you is sold or shared with data brokers. Ever.
What the app handles, and where it goes
This is the complete list. If something isn't in this table, the app doesn't touch it.
| What | Where it goes | Why |
|---|---|---|
| Your eToro API keys | Stored in your iPhone's Keychain. Sent only to eToro. | To read your portfolio. Never sent to me, never sent to any third party other than eToro itself. |
| Your portfolio and positions | Fetched from eToro to your iPhone. Sent to Anthropic if you use the AI summary. | To show you your holdings, and to write the summary if you ask for one. |
| Ticker symbols you hold | Yahoo Finance | To get current market prices. |
| Your settings and cached portfolio | Stays on your iPhone | So the widget has something to show between refreshes. |
Who else is involved
I have no servers. Where the app needs something it can't compute on your iPhone, it asks one of these services directly:
eToro
Your broker. The app talks to eToro's public API using the keys you provide. Your relationship and your data there are governed by eToro's own terms and privacy policy, not mine.
Yahoo Finance
Market prices for the symbols in your portfolio.
Writes the portfolio summary, if you use that feature. Your holdings are sent as part of the prompt. Anthropic does not use API content to train its models.
How long anything is kept
On your iPhone, for as long as you keep the app. I keep nothing, because I have nowhere to keep it — there is no backend, no database and no log of who uses the app. The third parties above keep what their own policies say they keep.
Deleting your data
Delete the app. iOS removes its storage, its caches and its Keychain items along with it, and there is no copy anywhere else. If you'd rather clear things without deleting the app, the app's own settings let you remove what it has stored.
Your rights
Under the GDPR you have the right to access, correct, delete and export your personal data, and to object to its processing. In practice, for this app there is almost nothing for me to act on: I hold no copy of your data, so there is no account of yours for me to look up.
What you can do yourself, right now, without asking me:
- Delete everything the app holds by deleting the app from your iPhone. iOS removes its storage, its cache and its Keychain items with it.
- Withdraw any permission in Settings → Privacy & Security, or in the app's own row in Settings.
If you want to exercise a right anyway, or you think I've got something wrong, write to hola@nachodivasson.com and I'll answer within 30 days. You can also complain to the Spanish data protection authority, the AEPD.
Children
This app is not directed at children under 13, and I do not knowingly collect anything from them.
Changes to this policy
If the app starts doing something new with your data, this page changes before the update ships, and the date at the top changes with it. I don't make changes retroactively.
Who is responsible
Ignacio Divasson, an individual developer based in Spain, is the data controller for this app.
